Hi, thank you for your efforts on improviing the fribidi manual page. Unfortunately, using help2man tends to not play well with cross compilation. The built fribidi cannot be run and help2man fails. There are many solutions to this problem none of which are nice. For instance, installing the manual page into an arch:all package would remove the need for it to be cross built, but that would be a very small arch:all package. Since fribidi is a very small packages with few dependencies, I suggest building it twice. A native pass is used to generate the manual page and then everything but the manual page is cross built. Implementing this for fribidi is a bit tricky. I've come up with the attached patch. I recognize that it does add quite a bit of complexity to the packaging, but please be aware that every known solution to the help2man problem has significant downsides. Is that something you're willing to apply? If not, please consider alternative solutions: * fribidi could Build-Depends: libfribidi-bin <cross> and use the built and installed version of the fribidi command to generate the manual page. * The help text could be extracted from the src/fribidi-main.c source code without running the built command (e.g. using Perl or Python) and be passed to help2man. * A cross build could skip generating a manual page. Doing so permanently renders cross builds unreproducible. * A real manual page that does not rely on help2man could be written. Additionally, I think that the command used to generate the manual page belongs into a verbose build log. Helmut
